Shoe for automatically adjusting and supporting foot arch

Abstract

The present invention discloses a shoe for automatically adjusting and supporting a foot arch, including: a shoe body; an elastic arch support member disposed in an interior of the shoe body, where the elastic arch support member includes an associated midsole, a foot arch support curved surface block disposed on the associated midsole, a spring body; several elastic straps disposed between an outer edge of the foot arch support curved surface block and the interior of the shoe body; and further including a pressure-bearing plate independently disposed between the associated midsole and an inner bottom portion of the shoe body. In the present invention, the foot arch support curved surface block is adapted to the foot arch, and the spring body and the elastic strap that have a flexible and adjustable function are disposed.

What is claimed is: 
     
       1. A shoe for automatically adjusting and supporting a foot arch, comprising: a shoe body; an elastic arch support member disposed in an interior of the shoe body and used for foot arch adaptive support, wherein the elastic arch support member comprises an associated midsole, a foot arch support curved surface block disposed on the associated midsole, and a spring body; several elastic straps disposed between an outer edge of the foot arch support curved surface block and the interior of the shoe body, wherein the foot arch support curved surface block is in direct contact with a human body foot arch when worn, the spring body is adapted to an inner bottom of the foot arch support curved surface block, and the spring body and the several elastic straps flexibly adjust a support force at the foot arch jointly; and further comprising a pressure-bearing plate independently disposed between the associated midsole and an inner bottom portion of the shoe body and used for bearing the support force when a gait of the foot arch changes. 
     
     
       2. The shoe for automatically adjusting and supporting a foot arch according to  claim 1 , wherein the foot arch support curved surface block is adapted to a shape of the human body foot arch when worn, and a thickness of the foot arch support curved surface block gradually decreases from a middle to two ends. 
     
     
       3. The shoe for automatically adjusting and supporting a foot arch according to  claim 1 , wherein the spring body is disposed at a lower edge of a middle bottom curved surface of the foot arch support curved surface block and has a thickness adapted to the foot arch support curved surface block, and the thicknesses of the spring body and the foot arch support curved surface block gradually decrease from the middle to the two ends. 
     
     
       4. The shoe for automatically adjusting and supporting a foot arch according to  claim 1 , wherein an outer edge of the foot arch support curved surface block is provided with several connecting members, the several connecting members are in one-to-one correspondence with the several elastic straps, one end of each elastic strap passes through the connecting member to be connected to the foot arch support curved surface block, and the other end of each elastic strap is connected to an inner upper portion of the shoe body. 
     
     
       5. The shoe for automatically adjusting and supporting a foot arch according to  claim 1 , wherein a connection manner between the elastic strap and the interior of the shoe body may be thread stitching or adhesive connection. 
     
     
       6. The shoe for automatically adjusting and supporting a foot arch according to  claim 1 , wherein the associated midsole is fixedly connected to the foot arch support curved surface block and the spring body through machine stitching or adhesive bonding. 
     
     
       7. The shoe for automatically adjusting and supporting a foot arch according to  claim 1 , wherein the associated midsole is fixedly connected to the interior of the shoe body or a vamp of the shoe body in a thread stitching manner. 
     
     
       8. The shoe for automatically adjusting and supporting a foot arch according to  claim 1 , wherein the spring body is made of a high-elasticity material; and the pressure-bearing plate is made of a high support material.
